II. ABSTRACT

Objective:

As a non-profit organization, gensan-buy.com is dedicated to provide the most

convenient access to Generals shoppers and patrons in promotions, discounts, gigs,

and quick reference to budget-conscious people.

This website has been developed to provide the most convenient way for

shoppers in which, they can access real time pricing of commodities in different

service providers of General Santos City and neighboring municipalities, cities and

regions.

Specific Objective of the site:

Objective of doing this project is to enhance knowledge in the field of e-commerce using

mainly php and htmlas a frontend and MySQL as the backend. Applying System

Analysis and Design principle through basic application and guidelines.

Addressing clients requirement and objectives of this site as follows:

To increase the business of Client/s.

To benchmark for a potential global advertising. To act as a middle men connecting Shoppers and Service Providers

User can search for different options available.

IV. SYSTEM ANALYSIS

Existing System

When the requirement of this system is putted before the team they was willing to know

that how the employee of the company is working. Then the study is done it gives the

result that all the work is done manually and there is nothing that help the employee to

save the time and do the work with the system. All the documentation is done by theemployee of the company. A lot of works have to be done before the candidates are

placed in an organization.

All that the company needs to store about the job seekers must be written on the

paper. Some times it is very difficult to know about some special highlights of the job

seeker, because the information is stored on the paper and it is not clear that due to

human error or by some other means this paper is lost and the information is now not in

the hands of the company.

At the time of hiring the companies policy says that the only those companies

can hire who are registered with SEEKJOB. So it is critical task to find out the registered

employer, when the company has so many employers.

There is extra requirement of employee who have to check that the requesting

person is an registered employer. This seams a critical task

Limitations

The current system have all the problems which generally in count in the manualsystem such as wastage of time, wastage of money, more efforts to work etc. if the

responsible person wants the full information of the total sale of various models of the

vehicles at various center at the evening then he/she can not get it. Because the current

system work manually and it is very slow same as if he/she wants the total production

then it take time. The current system can not give the fast response as needed. It also

5


6/77

does not keep records of grievances of the faults in the vehicles in various parts of the

country. If he/she wants the information regarding the total stock at various warehouses

at his\her office then using current system he\she can not get it.

He\she can not get the full information on time. It may be late and this process is time

consuming and generally the administrators receive the relevant information next day

which is the major limitation of existing system.

Proposed system:

This site is an attempt to make the task of administrator as well as jobseekers easier.

This project ensures the consistency by enabling the jobseekers to register themselves

and to find the desired information of jobs, get them involved with the jobsite and can

access the different services provided by the jobsite.

The administrator has the right to know everything. He has the right to know the details

of the jobseekers, has the right to change any service that the jobsite is currently

providing or can add services which are not being provided currently. Even the

customers passwords and hidden details are accessible by the administrator. Now

jobseekers are able to apply online also. Through this system all works are done

through computer so it results in fast service provider.

The jobseekers can also contact the company officials through email or his contactnumbers but first they have to register themselves as a member by filling up a

registration form which can be filled online. Once registered, jobseekers can access this

jobsite and register for any services being provided by seekjob.com, that too online by

sitting at home within a fraction of a second by a flick of a button.

Aim of this project is to provide an environment helpful for administrator and jobseekers

as well, so that, they find it easy to implement it without any harassment for the

jobseekers also. This project is developed after a

Through study of the existing manual system & the jobseekers requirements.

Requirement analysis is concerned with identifying the basic function of software

component in a hardware & software system.

7/77

Features of proposed system:

The features of the proposed system are as follows.

Provide the full information of employees/employer at various places at one site.

Provide the full information of total vacancies at various regions at one site.

Provide the full information of total vacancies of various industries/companies at one

site.

Helps the management to find out the current trend in industries as well as current

manpower pool.

V. RELATED STUDY

Feasibility Study:

A feasibility study is conducted to select the best system that meets performance

requirement. This entails an identification description, an evaluation of candidate system

and the selection of best system for he job. The system required performance is defined

by a statement of constraints, the identification of specific system objective and a

description of outputs.

The key consideration in feasibility analysis are:

Economic feasibility

The proposed system is economically feasible because the cost involved in purchasing

the hardware and the software are within approachable. The personal cost like salaries

of employees hired are also nominal, because working in this system need not required

a highly qualified professional. The operating-environment costs are marginal. The less

time involved also helped in its economical feasibility.

The benefits of this project include four types:

Cost saving benefits

7


8/77

This project reduces the administrative and operational cost. Because of the reduction

in the use of paper, use of labors the cost also reduces.

Improve-service-level benefits

Proposed system improves the systems performance because the current system is

based on manual processing while the proposed system is based on computer

processing.

Improve-information-level benefits

It provides better information in the stipulated space and time for decision-making.

Time-saving-benefits

It saves lots of time and provides the same result in a far lesser period of time.

Behavioral Feasibility

Employees of the company are habitual of working with manual system and dont

have the knowledge of working in a computer application based environment that is

used in their intranet and are generally resistant to make changes in their working

attitude.

9


10/77

People are inherently resistant to change and computers have been known to

facilitate changes. An estimate should be made of how strong a reaction the staffs are

likely to have towards the development of an online computerized system because now

this may lead to expulsion of some of the staffs from their jobs.

So a system has to be chosen which will provide them much more facilities and

less mental disturbance to check weather correct entry is entered and that too at its

right place. The System will provide them automatic reporting and checks on entries

while storing as well as entering. So the front end has been made user friendly for both

the jobseekers and the employees.

THE DATABASE

DATABASE DESIGN

In our data flow diagram, we give names to data flows, processes and data stores.

Although the names are descriptive of data, they do not dive details .So following DFD,

our interest is to build some details of the contents of data flows, processes and data

store. A data dictionary is a structured repository of data about data .It is a set of

rigorous definitions of all DFD data elements and data structures .The data dictionary

for the current system has been given as under:

TestingTesting plays a critical role in quality assurance for software .Due to the limitation of the

verification method for the previous phases, design and requirement fault also appear in

the code. Testing is used to detect these errors, in edition to the error introduced during

coding phase.

Testing is a dynamic method for verification and validation, where the system is to

be tested is executed and behavior of the system is observed. Due to this testing the

failure of the system can be observed, from which the presence of fault can be

deduced. However, separate activities have to be performed to identify the faults.

There are two method of testing: functional and structural. In functional testing,

the internal logic of the system under testing is not considered and the test cases are

decided from the specification or the requirements. It is often called Black Box Testing.

Equivalence class partitioning, boundary analysis, and cause effect graphing are

examples of methods for selecting test cases for functional testing. In structural testing,

the test cases are decided entirely on the internal logic of the program or module beingtested.

As the goal of testing is to detect any errors in the programs different flavor of

testing are often used. Unit testing are used to test a module or a small collection of

modules and the focus is on detecting coding errors in modules. During integration

testing modules are combined into sub-system, which are then tested. The goal here is

to test the system design. In system testing and acceptance testing, the entire System

is tested. The goal here is to test the requirement themselves. Structural testing can be

used for unit testing while at higher level mostly functional testing is used.

In the project Monthly Materialization Report System we used the unit testing

and functional testing. System testing is a critical phase in systems implementation.

Testing of a system involves hardware device testing and debugging of computer

programs and testing information processing procedures. Testing can be done with test

37


38/77

data, which attempts to simulate all possible conditions that may arise during

processing. The plane for testing are prepared and then implemented.

The testing methods adopted in the testing of the system were Independent Unit

Testing and System Testing

Independent Unit Test (IUT)

IUT focuses first on the modules, independently of one another, to locate errors. This

enables the tester to detect errors in coding and logic that are contained within that

module alone. Those resulting from the interaction between modules are initially

avoided.

IUT is generally white box oriented which is predicted on the close

examination of procedural detail. It exercises all the logical decisions on their true and

false side, executes all loops at their boundaries and within their operational bounds

and checks whether the required validations have been met. White box testing

exercises internal data structure to assure their validity.

SYSTEM TESTING

Here the system testing involved is the most widely used testing process consists of five

stages as shown in the figure. In general, the sequence of testing activities is

component testing, integration testing then user testing. However, as defects are

discovered at any one stage, they required program modifications to correct them and

this may required other stages in the testing process to be repeated.

38


39/77

(Component testing) (Integration testing) (User testing)

Testing is the process of detecting errors. Testing performs a very critical role for quality

assurance and for ensuring the reliability of the software. The results of testing are used

later on during maintenance also.

40/77

Testing is vital to the success of the system. System testing makes a logical assumption

that if the parts of the system are correct, the goal will be successfully achieved. In

adequate testing or non-testing leads to errors that may not appear until months or even

years later (Remember the New York three day power failure due to a misplaced Break

statement).

This creates two problems:

1. The time lag between the cause and the appearance of the problem.

2. The time interval effect of the system errors on files and the records on the system.

A small error can conceivably explode into a much larger problem. Effective testing

early in the process translates directly into long term cost savings from a reduced

number of errors.

Another reason for system testing is its utility as a user oriented vehicle before

implementation. The best program is worthless if it does not meet the user

requirements. Unfortunately, the users demands are often compromised by efforts to

facilitate program or design efficiency in terms of processing time or design efficiency.

Thus in this phase we went to test the code we wrote. We needed to know if the code

compiled with the design or not? Whether the code gave the desired outputs on given

inputs? Whether it was ready to be installed on the users computer or some more

modifications were needed?

Through the web applications are characteristically different from there software

counterparts but the basic approach for testing these web applications is quite similar.

These basic steps of testing have been picked from software engineering practices. The

following are the steps, we undertook:

40


41/77

1. The content of the Intranet site is reviewed to uncover Content errors. Content Errors

covers the typographical errors, grammatical errors, errors in content consistency,

graphical representation and cross referencing errors

2. The design model of the web application is reviewed to uncover the navigation errors.

Use cases, derived as a part of the analysis activity allows a web designer to exercise

each usage scenario against the architectural and navigational design. In essence

these non-executable tests help to uncover the errors in navigation.

3. When web applications are considered the concept of unit changes. Each web page

encapsulates content navigation links, content and processing elements (Forms,

Scripts, JSPs as in our case). It is not always possible to test each of these individually.

Thus is the base of the web applications the unit to be considered is the web page.

Unlike the testing of the algorithmic details of a module the data that flows across the

module interface, page level testing for web applications is driven by content,

processing and links encapsulating the web page.

4. The Assembled web application is tested for overall functionality and content delivery.The various user cases are used that test the system for errors and mistakes.

5. The Web application is tested for a variety of environmental settings and is tested for

various configurations and upon various platforms.

The modules are integrated and integration test are conducted.

1. Thread based testing is done to monitor the regression tests so that the site does not

become very slow is a lot of users are simultaneously logged on.

2. A controlled and monitored population of end users tests Intranet application, this all

comprises of the User Acceptance Testing.

41


42/77

Because web application evolves continuously, the testing process is an ongoing

activity, conducted by web support staff in our case the Organizations IS people who

will finally update and manage the application.

PSYCHOLOGY OF TESTING

The aim of testing is often to demonstrate that a program works by showing that it has

no errors. The basic purpose of testing phase is to detect the errors that may be present

in the program. Hence one should not start testing with the intent of showing that a

program works, but the intent should be to show that a program doesnt work. Testing is

the process of executing a program with the intent of finding errors.

TESTING OBJECTIVES:

The main objective of testing is to uncover a host of errors, systematically and with

minimum effort and time. Stating formally, we can say,

1. Testing is a process of executing a program with the

intent of finding an error.2. A successful test is one that uncovers an as yet

undiscovered error.

3. A good test case is one that has a high probability of

finding error, if it exists.

4. The tests are inadequate to detect possibly present

errors.

5. The software more or less confirms to the quality and

reliable standards.

LEVELS OF TESTING

42


43/77

In order to uncover the errors present in different phases, we have the concept of levels

of testing. The basic levels of testing are

Client Needs Acceptance Testing

Requirements System Testing

Design Integration Testing

Code Unit Testing

Unit testing

Unit testing focuses verification effort on the smallest unit of software i.e. the module.

Using the detailed design and the process specifications, testing is done to uncover

errors within the boundary of the module. All modules must be successful in the unit test

before the start of the integration testing begins.

In this project each service can be thought of a module. There are so many modules

like Login, HR Department, Interviewer Section, etc. Each module has been tested by

giving different sets of inputs. When developing the module as well as finishing the

development, the module works without any error. The inputs are validated when

accepting them from the user.

Integration Testing

After unit testing, we have to perform integration testing. The goal here is to see if

modules can be integrated properly, the emphasis being on testing interfaces between

43


44/77

modules. This testing activity can be considered as testing the design and hence the

emphasis on testing module interactions.

In this project the main system is formed by integrating all the modules. When

integrating all the modules I have checked whether the integration effects working of

any of the services by giving different combinations of inputs with which the two

services run perfectly before Integration.

SYSTEM TESTING

Here the entire software system is tested. The reference document for this process is

the requirements document, and the goal is to see if software meets its requirements.

Here entire HRRP has been tested against requirements of project and it is checked

whether all requirements of project have been satisfied or not.

ACCEPTANCE TESTING

Acceptance Testing is performed with realistic data of the client to demonstrate that the

software is working satisfactorily. Testing here is focused on external behavior of the

system; the internal logic of program is not emphasized.

Test cases should be selected so that the largest number of attributes of an equivalence

class is exercised at once. The testing phase is an important part of software

development. It is the process of finding errors and missing operations and also a

complete verification to determine whether the objectives are met and the user

requirements are satisfied.

WHITE BOX TESTING

This is a unit testing method, where a unit will be taken at a time and tested thoroughly

at a statement level to find the maximum possible errors.

44


45/77

I tested step wise every piece of code, taking care that every statement in the code is

executed at least once. The white box testing is also called Glass Box Testing.

I have generated a list of test cases, sample data, which is used to check all possible

combinations of execution paths through the code at every module level.

White-box test focuses on the program control structure. Test cases are derived

to ensure that all statement in the program control structure. Test cases are derived to

ensure that all statement in the program control structure. Test cases are derived to

ensure that all statement in the program has been executed at least once during testing

and that all logical conditions have been exercised. Basis path testing, a white box

technique, makes use of program graphs (or graph matrices) to derive the set of linearly

independent test that will ensure coverage. Condition and data flow testing further

exercising degrees of complexity.

BLACK BOX TESTING

This testing method considers a module as a single unit and checks the unit at interface

and communication with other modules rather getting into details at statement level.

Here the module will be treated as a block that will take some input and generate

output. Output for a given set of input combinations are forwarded to other modules.Black-box test are designed to uncover errors functional requirement without

regard to the internal workings of a program. Black-box testing techniques focus on the

information domain of the software, deriving test cases by partitioning the input and

output domain of a program in manner that provides through test coverage. The black-

box test is used to demonstrate that software functions are operational, that input is

properly produced, and that the integrity of external information is maintained. A black-

box test examines some fundamental aspect of a system with little or no regard for the

integral logical structure of the software.

Graph based testing methods explore the relationship between and behavior of

program objects. Equivalence partitioning divides the input classes of data are likely to

45


46/77

exercise specific software function. Boundary values analysis probes the programs

ability to handle data at the limits of acceptability.

TEST INFORMATION FLOW

A strategy for software testing may also be viewed in the context of the spiral. Unit

testing begins at the vortex of the spiral and, concentrates on each unit, component of

the software as implemented in source code. Testing progresses moving outward along

the spiral to integration testing, where the focus is on designed the construction of the

software architecture. Taking another turn outward on spiral, we encounter validation

testing, where requirements established as part of software requirements analysis are

validated against the software that has been constructed. Finally, we arrive at systemtesting, where the software and other system elements are tested as a whole. To test

computer software, we spiral out along stream lines that broaden the scope of testing

with each turn.

Considering the process from a procedural point of view, testing within the context

of software engineering is actually a series of four steps that are implemented

sequentially. The steps are shown in Figure. Initially, tests focus on each component

individually, ensuring that it functions properly as unit. Hence, the name unit testing.

Unit testing makes heavy use of white-box testing techniques, exercising specific paths

in modules control structure to ensure complete coverage and maximum error

detection.

System Security

SYSTEM SECURITY

There are basically two types of security associated with this system:-

1. Physical security:-

Damage due to natural causes like earth tremor, flooding, water logging, fire

hazards, atmospheric or environmental conditions etc.For overcoming these difficulties

the replica of the data are automatically stored at various networks and for

environmental conditions Air conditioning environment is created.

2. Data security:-

There are basically two problems associated with data security:-

1. Data not being available to the authorized person at the time of need.

2. Data becoming available to the unauthorized person.

To overcome these difficulties the following access facilities has been provided:-

i) Identification:-

Unique Ids for the different users have been provided.

ii) Authentication:-

47


48/77

System checks the password under the particular user identification. The

computer permits the various resources to the authorized person.

iii) Authorization:-

The access control mechanism to prevent unauthorized logging to the system.

48


49/77

IMPLEMENTATION

System implementation is the stage when the user has thoroughly tested the system

and approves all the features provided by the system. The various tests are performed

and the system is approved only after all the requirements are met and the user is

satisfied.

The new system may be totally new; replacing an existing manual or automatedsystem, or it may a major modification to an existing system. In the either case, proper

implementation is essential to provide a reliable system to meet organization

requirements .successful implementation may not guarantee improvement in the

organization using the new system (that is a design question) ,but improper will prevent

it.

MAINTENANCE

Software maintenance is the last phase in the software Engineering process that

eliminates errors in the working system during its work span and to tune the system to

any variations in its working environment. The system requires maintenance as there

may be changes and requirements in the organizational needs, government policies,

hardware and software environment etc. often small system deficiencies are found as a

system is brought into operation and changes are made to remove them. System

requirements may be revised as a result of system usage or changing operational

needs. Perhaps oversight that occurred during the development process needs to be

corrected. Often the maintenance need arises to capture additional data for storage in a

database or in transaction files or perhaps it may be necessary to add error detection

features to prevent system users from in adversely taking an unwanted action.

Maintenance of the system after it is installed is concerned with an additional

factor in hardware. Once the system is delivered and installed there is a brief warranty

period during which time the vendor is responsible for maintenance. This is a typically a

52


53/77

90 day period after that time the purchaser has the option of acquiring maintenance

from various sources. Maintenance source excepting vendor is also available from

companies specializing in providing the service, called third party maintenance

companies.

When the system is installed, it is generally used for long period. The average life of

system is 4-6 years, with the eldest applications often is used for over 10 years. The

need for debugging and correcting errors or failure on an emergency basic is

comparatively low: less than 20% of the task of correction. System and organization are

in constant state of flux; therefore the maintenance of the system also involved

adoptions for earlier version of software.

Approximately 20% of all maintenance work is performed to accommodate

changes in report, files and database. The greatest amount of maintenance work is for

user enhancement, improved documentation and recording system components or

greater efficiency. About 60% of all maintenance is for this purposed.

FUTURE SCOPE OF THIS PROJECT

In future this project can be treated as product according to specification and needs of

any organization.

Since Jobseeker plays key role in any organization; thus, success over a long period of

time and reliance of organization over recruitment is going to be one of the most

considered topic for any organization. Therefore Jobs seeker Process will be of great

help in carrying out recruitment process smoothly and effectively.

At present days every organization is using web technology for their proper functioning,

so this web based project is all in all important from market aspects.

Furthermore if this project will be uploaded, it can be used as Jobs site and any

organization can register their self on the site to carry out their recruitment process

making this site as Jobs seeker.

LIMITATIONS

Since, every system has some limitations so our proposed system is also not

untouchable in this regard. Although it includes every kind of features but it cant be

used in a huge organization where number of networks are very large, because the data

base used in this system is an average one. Also it doesnt have different kind of access

feature for different users.

SOFTWARE SCOPE

Reusability:

Reusability is possible as and when we require in this application. We can

update it next version. Reusable software reduces design, coding and testing cost by

amortizing effort over several designs. Reducing the amount of code also simplifies

understanding, which increases the likelihood that the code is correct. We follow up

both types of reusability: Sharing of newly written code within a project and reuse of

previously written code on new projects.

Extensibility:

This software is extended in ways that its original developers may not

expect. The following principles enhance extensibility like Hide data structure, avoid

traversing multiple links or methods, Avoid case statements on object type and

distinguish public and private operations.

Robustness:

58


59/77

Its method is robust if it does not fail even if it receives improper

parameters. There are some facilities like Protect against errors, Optimize after the

program runs, validating arguments and Avoid predefined limits.

Understandability:

A method is understandable if someone other than the creator of the

method can understand the code (as well as the creator after a time lapse). We use the

method, which small and coherent helps to accomplish this.

Cost-effectiveness:

Its cost is under the budget and make within given time period.

It is desirable to aim for a system with a minimum cost subject to the condition that it

must satisfy all the requirements.

Scope of this document is to put down the requirements, clearly identifying the

information needed by the user, the source of the information and outputs expected

from the system.

APPENDIX-A

Backend remains on server side and has two components i.e.

1. Server side program

2. Data Base.

Data base is the most important thing in this universe as data base gives identity to a

thing without data base existence of a thing is impossible while working on a project first

step is to design a database.

What is data base?Data Base is a collection of tables and table is a collection of records in a tabular form

i.e. in row and columns.

Data Base can be divided into two parts:-

1. RDBMS.

2. DBMS.

We will be using RDBMS (Relational Database Management System) in our project i.e.

oracle 8i Enterprise edition.

Why we are using Oracle (RDBMS)?

Some of the merits of using Oracle (RDBMS) are as under:-

Centralization of database.

Client Server Technology.

Security.

Normalization of Data Base.

Relationship.

Transaction Processor.

It gives some internet related features.

Hence because of these features we are using Oracle as a back end technology.

APPENDIX-BWhat is Middle Ware?

Middle Ware is a concept, Middle Ware provides centralization of business logic i.e.

instead of putting logic on each and every client machine we put logic on a centralized

server hence middle ware is nothing but a server side program where all your business

logic and business methods reside. It remains on server side and it has all the logical

building. Middle ware provides:-

1. Multiple Client access.

2. Centralized business logic in case of distributed application.

Because we are working on Distributed Application Based Project we need platform

independent Language:-

Technology Used

Introduction to Java

Java is a high level, third-generation programming language, like C, Fortran, Perl and

many others. It is a platform for distributed computing a development and run-time

environment that contains built-in support for the World Wide Web.

History of Java

Java development began at Sun Microsystems in 1991, the same year the World Wide

Web was conceived. Javas creator, James Gosling did not design java for the Internet.

His Objective was to create a common development environment for consumer

electronic devices which was easily portable from one device to another.

This effort evolved into a language, code named Oak and later renamed Java thatretains much of the syntax and power of c++, but is simpler and more platform

independent.

Java Features

Some of the important features of Java are as follows:

Simplicity

65


66/77

Orientation

Platform Independence

Security

High Performance

Multi Threading

Dynamic linking.

Garbage Collection.

One of the most important features of Java is Platform Independence which makes it

famous and suitable language for World Wide Web.

Why java is Platform Independent?

Java is Platform Independent because of Java Virtual Machine (JVM).

Java Virtual Machine (JVM)

The client application or operating system must have a java byte-code interpreter to

execute byte-code instructions. The interpreter is a part of a lager program called the

JVM. The JVM interprets the byte code into native code and is available on a platform

that supports java.

Connectivity using JDBC

There are four kinds of drivers available in Jdbc:-

1. JdbcOdbc Bridge Driver.

2. Partly Java Driver.

3. Pure Java Driver.

4. Native Driver.

Client Side Interface:In client side interface we are using:-

Servlet / JSP In Internet Based Application.

J2EE Framework and Architecture

J2EE is one of the best solutions that we have had so far for meeting the demand of

todays enterprise. J2EE specifies both the infrastructure for managing our applications,

and the service APIs for building our applications.

The J2EE platform is essentially a distributed application-server environment- a java

environment that provides the following: -

A set of java extension APIs to build applications. These APIs define a programming

model for J2EE applications.

A run time infrastructure for hosting and managing applications. This is the server

runtime in which our applications resides.

The applications that we could develop with the above may be programs to drive web

pages, or components to implement complex database transactions, or even java

applets, all distributed across the network.

The J2EE Runtime

While J2EE bundles together APIs that have been in existence in one form or another

for quite sometime, perhaps its most significant aspect is the abstraction of the runtime

infrastructure. The J2EE specification doesnt specify how a J2EE runtime should or

could be built. Instead, J2EE specify roles and interfaces for applications, and theruntime onto which applications could be deployed. This results in a clear demarcation

between applications and the runtime infrastructure. This demarcation allow the runtime

to abstract most of the infrastructure services that enterprise developers have

traditionally attempt to build on their own. As a result, J2EE application developers

could just focus on the application logic and related service, while leveraging the

runtime for all infrastructure-related services.

Apart from specifying a set of standard APIs, the J2EE architecture also provides a

uniform means of accessing platform-level services via its runtime environment. Such

service includes distributed transactions, security, messaging etc.

The J2EE APIs Used

Distributed applications require access to a set of enterprise services. Typical services

include transaction processing, database access, messaging, multithreading etc. The

67


68/77

J2EE architecture unifies access to such services in its enterprise service APIs.

However, instead of having to access these service through proprietary or non standard

interfaces, application programs in J2EE can access these APIs via the container.

There are various API specification in J2EE framework which enable us to create an

application at great speed with minimum effort.

APIs Used To Build the Software

1. JDBC API

The JDBC API provides developers with a way to connect to relational data from

within java code. Using the JDBC API, developers can create a client (which can be

anything from an applet to an EJB) that can connect to a database, execute structured

query language statements, and processes the result of those statements. The API

provides connectivity and data access across the range of relational databases. It can

do this because it provides a

set of generic database access methods for sql compliant relational databases. JDBC

generalizes the most common database access functions by abstracting the vendor

specific detail of particular database. The result is set of classes and interface, placed in

the java.sql package, which can be used with any database that has an appropriate

JDBC drive. This allow JDBCconnectivity to be provided in a consistent way for any database. It also means that with

a little care to ensure the application confirms to the most commonly available database

features, an application can be use with a different database simple by switching to a

different JDBC driver. JDBC includes following packages for the means of database

accessing and provides various features of the database. The packages are as follows:

-

java.sql Package: -

This package contains classes and interfaces designed with traditional client/server in

mind. Its functionality is focused primarily on basic database programming services

such as creating connections, executing statements and prepared statements, and

running batch queries. Advanced functions such as batch updates, scrollable result

sets, transaction isolation, and sql data types are also availabl

68


69/77

javax.sql Package: -

This package introduces sum major architectural change to JDBC programming

compared to java.sql package, and provides better abstractions for connections

management, distributed transactions, and legacy connectivity. This package also

introduces container-managed connection pooling, distributed transactions, and row

sets.

2. Java Servlets: -

Servlets are Java technologys answer to Common Gateway Interface (CGI)

programming. They are programs that run on a Web server, acting as middle layer

between a requests coming from a Web browser or other HTTP client and databases or

applications on the HTTP server. Their job is to:

Read any data sent by the user.

This data is usually entered in a form on a Web page, but could also come from a Java

applet or a custom HTTP client program.

Look up any other information about the request that is embedded in the HTTP

request.

This information includes details about browser capabilities, cookies, the host name of

the requesting client, and so forth.Generate the results.

This process may require talking to a database, executing an RMI or CORBA call,

invoking a legacy application, or computing the response directly.

Format the results inside a document.

In most cases, this involves embedding the information inside an HTML page.

Set the appropriate HTTP response parameters.

This means telling the browser what type of document is being returned (e.g., HTML),

setting cookies and caching parameters, and other such tasks.

Send the document back to the client.

This document may be sent in text format (HTML), binary format (GIF images), or even

in a compressed format like gzip that is layered on top of some other underlying format.

Many client requests can be satisfied by

69


70/77

returning pre-built documents and these requests would be handled by the server

without invoking servlets. In many cases, however, a static result is not sufficient, and a

page needs to be generated for each request.

Java Server Pages: -

Java Server Pages (JSP) technology enables you to mix regular, static HTML with

dynamically generated content from servlets. Many Web pages that are built by CGI

programs are primarily static, with the parts that change limited to a few small locations.

For example, the initial page at most on-line stores is the same for all visitors, except for

a small welcome message giving the visitors name if it is known. But most CGI

variations, including servlets, make you generate the entire page via your program,

even though most of it is always the same. JSP lets you create the two parts separately.

Listing 1.1 gives an example.

Most of the page consists of regular HTML, which is passed to the visitor

unchanged. Parts that are generated dynamically are marked with special HTML-like

tags and mixed right into the page.

The Advantages of JSP

JSP has a number of advantages over many of its alternatives. Here are a few of them.

Versus Active Server Pages (ASP)ASP is a competing technology from Microsoft. The advantages of JSP are twofold.

First, the dynamic part is written in Java, not VBScript or another ASP-specific

language, so it is more powerful and better suited to

complex applications that require reusable components. Second, JSP is portable to

other operating systems and Web servers; you arent locked into Windows NT/2000 and

IIS. You could make the same argument when comparing JSP

to ColdFusion; with JSP you can use Java and are not tied to a particular server

product.

Versus Pure Servlets

JSP doesnt provide any capabilities that couldnt in principle be accomplished with a

servlet. In fact, JSP documents are automatically translated into servlets behind the

70


71/77

scenes. But it is more convenient to write (and to modify!) regular HTML than to have a

zillion println statements that generate the HTML. Plus, by separating the presentation

from the content, you can put different people on different tasks: your Web page design

experts can build the HTML using familiar tools and leave places for your servlet

programmers to insert the dynamic content.

Versus Server-Side Includes (SSI)

SSI is a widely supported technology for inserting externally defined pieces into a

static Web page. JSP is better because you have a richer set of tools for building that

external piece and have more options regarding the

stage of the HTTP response at which the piece actually gets inserted. Besides, SSI is

really intended only for simple inclusions, not for real programs that use form data,

make database connections, and the like.

Versus Static HTML

Regular HTML, of course, cannot contain dynamic information, so static HTML pages

cannot be based upon user input or server-side data sources. JSP is so easy and

convenient that it is quite reasonable to augment HTML pages that only benefit slightly

by the insertion of dynamic data. Previously, the difficulty of using dynamic data

precluded its use in all but the most valuable instances.

APPENDIX-C

What is HTML?

HTML (Hyper Text Markup Language): A markup language used to structure text andmultimedia documents and to set up hypertext links between documents, used

extensively on the World Wide Web. HTML is a display language, not a programming

language. HTML is a markup language (the ML in HTML) that uses a fixed set of

markup tags.

71


72/77

HTML itself is the set of customizable markup tags that are inserted into HTML

document govern its format, multimedia content, and hyperlinks. Any HTML viewer can

display such documents but they are normally viewed usinga Web browser.

HTML is a programming language in that an HTML document is a program that, when

run by a browser, displays its text as hypermedia (multimedia with hyperlinks).

The language HTML is really only a collection of predefined tags which , when

inserted into regular text, tell a web browser how to:

a. Format the document and its text.

b. Incorporate i.e. insert a graphic image, video sequence, or sound clip into the

displayed document.

c. Link into other locations, in the same document, in another web page, or even on

another computer (Server), or

d. Link to other programs written in Java, JavaScript or other languages (called CGI

applications).

Features of HTML:-

HTML stands for Hyper Text Markup Language.

An HTML file is a text file containing small markup tags.

The markup tag tells the Web browser how to display the page.

An HTML file must have an htm or html file extension.

An HTML file can be created using a simple text editor.

Its a display-only technology.

APPENDIX-D

What is JAVASCRIPT?

JavaScript is a compact, object-based scripting language. It can provide

interactive web pages, validate from data, and make your web page clearer. JavaScript

is a lightweight interpreted scripting language. The language is most well known for its

use in wesites.It was originally developed by Brendan Each of Netscape

Communications. It adds interactive functions to HTML pages, which are otherwise

static. JavaScript is easier to use than Java, but not as powerful and deals mainly with

72


73/77

the elements on the Web page. On the client, JavaScript is maintained as source code

embedded into an HTML page. On the Server, it is compiled into byte code

(intermediate language), similar to Java programs.

Features of JavaScript:-

JavaScript was designed to add interactively to HTML pages.

JavaScript is a scripting language-a scripting language is a lightweight programming

language.

A JavaScript is usually embedded directly in HTML pages.

A JavaScript is an interpreted language (means that script execute without preliminary

compilation).

All major browsers, like Netscape and Internet Explorer, support JavaScript.

Functions of JavaScript:-

JavaScript gives you the ability to perform the following functions:

Control document appearance and content

Control the browser

Interact with document content

Interact with the user

Read and write client state with cookies

Interact with applets

Manipulate Embedded Images

Limitations of JavaScript:-

JavaScript does not have any graphics capabilities

Client-side JavaScript can not read or write files

JavaScript does not support networking of any kind

JavaScript doesnt have any multithreading capabilities.
